This is an article on improving the efi on your Z car. Stuff you can do without special equipment. It's not really anything new from what we've discussed in the forums here. I read about this from a guy selling vacuum hose kits for a 280Z. He said in his auction that you can request a free copy, but what you get is a link to his website. It's 45 pages if you print it, but I would suggest that you just read sections instead.

I saw that a couple of years ago. There's really nothing there that's different from other info available such as Atlantic Z, etc.

The car in the article was an Alfa Romeo GTV6, so you need to find the ground points that the author is talking about. The Atlantic Z article just gives you general suggestions, and a few specific points (like the thermotime sensor.) But since this article is specific the Bosch L-jetronic EFI system, the grounds, connectors, etc., are there, just probably in a slightly different location.

But remember, the system that Datsun used is an adaptation of the Bosch system. Not everything that you read on the German and Italian cars applies.

No, it won't be all the same things in the same places, but learning about the basics, and what makes things happen, will help you. Things like the grounding points (mine were different) and the AFM & sensors.

I'm happy that you find it interesting. Like I said, I saw it a couple of years ago and didn't think it was really of much use considering that there is better and more applicable info available IMO.
